Micro-Trains - 520 00 193 - Stock Car, 40 Foot, Wood - Union Pacific - 48017D

Prototype History: Alonzo Mather, a Chicago clothing merchant who founded the Mather Stock Car Company, designed a new stock car in 1880 that was among the first to include amenities for feeding and watering the animals while en route. Mather was awarded a gold medal in 1883 by the American Humane Association for the humane treatment afforded to animals in his stock cars. Minneapolis' Henry C. Hicks patented a convertible boxcar/stock car in 1881, which was improved in 1890 with features that included a removable double deck. George D. Burton of Boston introduced his version of the humane stock car in 1882, which was placed into service the following year. The Burton Stock Car Company's design provided sufficient space so as to allow the animals to lie down in transit on a bed of straw. All-wood 40' stock cars of this general type would most likely have seen service in the early part of the 20th century (say, 1910-1930).

Road Name History: The Union Pacific Railroad (reporting mark UP) is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and employs 42,600 people. It is also one of the world's largest transportation companies.

Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).

Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.S.

Brand/Importer Information: Micro-Trains Line split off from Kadee Quality Products in 1990. Kadee Quality Products originally got involved in N-Scale by producing a scaled-down version of their successful HO Magne-Matic knuckle coupler system. This coupler was superior to the ubiquitous 'Rapido' style coupler due to two primary factors: superior realistic appearance and the ability to automatically uncouple when stopped over a magnet embedded in a section of track. The success of these couplers in N-Scale quickly translated to the production of trucks, wheels and in 1972 a release of ready-to-run box cars.

Micro-Trains Line Co. split off from Kadee in 1990 to form a completely independent company. For this reason, products from this company can appear with labels from both enterprises. Due to the nature of production idiosyncrasies and various random factors, the rolling stock from Micro-Trains can have all sorts of interesting variations in both their packaging as well as the products themselves. When acquiring an MTL product it is very important to understand these important production variations that can greatly enhance (or decrease) the value of your purchase.
